Built for Real Farm Work
Your 2630 and 2640 series tractors are the backbone of countless farming operations—reliable workhorses perfect for everything from field work to loader duties. These 4.19-inch bore engines are known for their durability, and with a proper rebuild using quality parts like these, you’re looking at many more years of dependable service. Whether you’re running hay equipment or working cattle, this engine will be ready for whatever you throw at it.
Made to Last
This Tru-Power kit uses OEM-spec materials and tolerances to ensure your rebuilt engine performs like new. The three-ring pistons provide excellent sealing while the hardened valve seats handle the heat and pressure of continuous operation. Every component is manufactured to handle the demands of farm work—because when you’re counting on your tractor for your livelihood, good enough isn’t good enough.
Good to Know
This is a complete overhaul kit minus bearings—you’ll need to measure your crankshaft and order rod and main bearings separately for proper clearances. Most rebuilders prefer this approach since bearing selection depends on actual measurements. Take your time with the assembly and follow torque specifications exactly. A proper rebuild now means years of trouble-free operation ahead.
